If Edwin digs too deep into the Club Carnations rabbit hole, he may just end up like his predecessor. I don't think Chuck expected Kat to take such an interest in Edwin and become his de facto mentor, especially since Ian is very disintersted in the workings of the club itself, only caring about the pussy it gets him, most likely expecting Edwin to be the same. Edwin's curiosity might bring hin to a bad end.
I suspect Victoria will come sniffing around too, since she's been suspicious of Edwin's activities for a while, especially since he started mentioning Chuck and August to her. August most likely used to be her producer/pimp, and Chuck was maybe one of her nastier clients, especially given his sexual "proclivities". So if Edwin tries to get out of the spider's web, or Vicky tries to investigate further, there may just be some nasty stuff in store for them, especially since Edwin already knows too much.
